SAW J OI NTER Filed April 9, 1931 Inventor (@7265 Wa'ss A Home y Patented June 13, 1933 Thisinvention relatestoasaw jointer; particularly for on cross cut saws and has i 1 forjits primary object to provide, i nIa 1nan- Tier as' hereinafter set forth, a device of this character embodying a novel construction and arrangement of parts, through the medium of "whiclii the cutting and rake-r teeth or the saws Inay be expeditiously filed in an.

.. accurate, uniform manner. 10

The foregoing and still further objects and advantages of the invention will become fapparentffrom a istudylof the following specification, taken in connection with theaccompanying drawing wherein like characters of reference designate like corresponding partsthroughout the several views, and wherein:-

. Referring to the dra mg in detail, it will be seen that the referencenumeral 1 desig i. nates an elongated metallic frame which is preferably substantially rectangular in form. The frame is also of skeleton form to render samelightin weight. Formed integrally with one ofthe longitudinal marginal por tions ofthe frame 1 and extending laterally in opposite directions therefrom are the flanges 2 and3. p p

Depending from oneend portion of the flange 2 is a lug 4 which is disposed slightly 1 is secured in position through the medium above the horizontal plane of an elongated lug 5 which projects from an intermediate portion of the adjacent side of the frame 1. A file 6 rests on the lug 5 and abuts the lug 4 and of a set screw 7 which is threaded through the other end portion of the flange 2 for. operative engagement with the file.

Flanges 21 are mounted on said'other mar-- ginal portion of the frame 1 on opposite sides of the recess through the medium of the right angularly disposed supporting portions F 22 having vertical slots 2 3 therein for 'the passage iOf the securing screws 24 which are threaded. into the frame 1. I

It will be noted that the supporting portions 22 of the adjustable'flanges 21 are secured to the side of the frame 1 upon which the-supporting leg or arm 12 of the gage plate llis secured. The adjustable flanges 21 extend across the frame 1 for engagement by the cutting teeth 8r of the saw 9 when the raker, teeth ofsaid saw arebeing filed. Lon- .gitudinally extending flanges 25 are formed integrally on one side of the frame 1 adjacent the free longitudinal edges of the supporting portions 22 of the adjustable flanges fall within the scope of the invention as claimed.

Having thus described my invention, what I claim as new is A saw j ointer comprising a frame, a flange at one side of the top edge of the frame and disposed substantially at right angles thereto, said flange extending from one end of the frame to the other end thereof, a lug formed' at one end o'f the flange and depending'therefrom and having a flat lower end offconsiderable' area, a longitudinally extending lug of considerable length formed on the central portion of said one side of the frame with itsupper face flat and spaced below the plane of the lower-end ofthe first-named lug, whereby a file can be placed lengthwise between the lugs with part of one face engaging the first-mentioned lug, and a part of the other face engaging the flat face of the second-mentioned lug, and a screw threaded through the other end of the flange for opera tive engagement with another part of the idle to bind said file frictionally against the u s. i s V I Tntestimony whereof I afiix my signature.

21 andthreaded therethrough are the screws 26 which provide positive supports for the adjustable flanges 21, and which also facilitate adjustment of saidflanges 21. At their inner ends, the flanges '25,merge with the spaced, vertically disposed guide flanges 27 betweenjwhiclrthe supporting leg or armpor- ;tions 12 of the gauge plate 11 is operable.

.The guide @flanges are also, of course, formed integrally with the frame 1. The 1 frame 1- is still further provided with the integral laterally projecting flanges, 28 which are longitudinally disposed and which have their free longitudinal edges. flush with the .outr'edge of. the flange 3. The flanges 3 and 28gareadapted for abutting engagement with one side of the saw 9 when the'r'aker teetl 20 of said saw are being filed.)

It will hus be seen that the flanges 21 which are engaged bythe-cutting teeth 8 of theisaw when. the-raker teeth of said saw are being filed, are adjustable as is also the gauge plate 11 and by reason of this fact, a .wide range of adjustment is had.

After; the various elementsare adjusted as .desired,--;-the raker teeth are, of course, inserted throughnthe slot 19 and the upwardly projecting portions thereof, are ifiled. in an iobviousmanner. I It'is believed that the many advantages of a saw jointer constructed in accordance with this invention will bereadily understood,.-.and although the preferred embodiment of the 'invention'is as illustrated and described, it is to be understood; that changes in the detai .Q ns ti ns may e ha W i -w l
